RAIL TRANSPORTATION

  • It is the movement of multiple wagons or a train of wagons with steel wheels over two parallel steel rails , that offers comparatively lesser resistance
  • Hence the cost of Transportation by this method is approx 1/6th of that by road transportation but it is less flexible comparatively
  • Railways are considered as a qrteries of entries transportation system

WATER TRANSPORTATION

  • It offers minimum resistance to traction hence cheapest method amongs the all
  • But the time required in this case comparatively more
  • It is suitable for transportation of bulk goods of relatively low valley

AIR TRANSPORTATION

  • It is the fastest method amongst all transportation but cost involved in this is also very high
  • It is suitable for transportation of high value goods on long hauls
  • This method is effected by weather conditions like storms , fog

ROAD TRANSPORTATION

  • It is the most flexible mode of transportation amongst the all
  • it consumes petrolium product at highest rate 
  • Major road transportation is archived by highway and expressway

Highways are special type of roads , designed to allow high speed of vehicles. 

It is generally constructed on embankment as

  • Better drainage facility
  • Safety in flood time
  • No lateral entry of public / animals

Example:- National Highway( NH ) , State Highway ( SH )

Expressways are superior type of Highway which are designed as direct source of connectivity between two defined places
